Admission related

Hi, I've been allotted nit rourkela industrial design branch. I'm from a rural village and my father is a farmer and has a small shop in our village, I had done self study and now joining college. I have a under 1 lakh income certificate that's signed by tehsildar. I'm a bit hesitant that they'll question me about absurdly low income as the one who appoints the income certificate just simply check the land records and estimate the income as farming is very volatile it depends on various factors.

But will I be alone who has a under 1 lakh certificate? Will I be questioned or background checked about?

I'm scared if they cancel my admission or just do a case on me.

The certificate is not forged. It's completely valid.
